Nautilus 11 Buyer's Guide
The Nautilus 11m is a 36-foot cutter built by Aztec Yachts from 1981 through 1990, with only five hulls produced and a lead-ballasted solid-fiberglass hull underneath a conservative cruising rig. For a shopper on the used market, the rarity means each boat stands on its own survey, but the known geometry and construction type give a clear frame for what to expect.
Layouts on the Used Market
The Nautilus 11 shows no layout variations, and the small build count argues against meaningful option packages. Buyers should treat the 28-foot waterline and 11.5-foot beam as the only reliable volume clues and inspect each hull individually.
Equipment and Common Upgrades
A swim platform is commonly fitted on Nautilus 11 boats offered in Canada, the one regional market where these hulls typically appear. Beyond that single recurring item, the available market record carries no often-seen or occasional owner upgrades, so a buyer should evaluate canvas, winches, and electronics on a per-boat basis rather than against a known equipment baseline.
What to Inspect
The Nautilus 11m shows no structural defects, osmotic hull damage, rigging failures, or systemic construction faults. Because only five were built, field history is thin; a buyer should still commission a full survey focused on the solid-fiberglass hull and deck for hidden impact damage and on the cutter rig's 14 mm sheet runs for chafe, since the original specifications size those lines at 36 to 90 feet in length guiding dimension for the genoa sheet. Confirm the fin-keel attachment, and treat any undocumented modification as a survey item rather than a standard feature.
Availability and Buyer's Takeaway
These boats are typically found in Canada. A short buyer checklist:
- Survey the solid fiberglass hull and deck for impact or osmosis.
- Inspect fin-keel bolts and spade-rudder stock.
- Verify diesel engine operation and mounts.
- Check cutter rigging for 14 mm sheet wear.
- Confirm swim platform attachment if fitted.
